CHRISTOPHER O. BRADLEY, OF SYRAOUSE, NEW YORK.

HARVESTER.

SPECIFICATION forming part of Letters Patent No. 245,343, dated August 9, 1881.

Application filed April 27, 1881. (No model.)

T0 all whom tt may concern Be it known that I, CHRISTOPHER C. BRAD- LEY, of Syracuse, New York, have inventeda new and useful Improvement in Harvesters, of which the following is a specification.

This invention relates to harvesters of the type invented by me, and patented to mein and by Letters Patent No. 236,209, dated J annary 4, 1881, being especially applicable to machines embodying thefeatures of construction of the main frame and minor axle typified in such machine.

My present invention relates to the improved construction of the following parts, viz: the box of the crank-shaft, which is made replaceable, and the journals ofthe main axle and otl the minor axle, which is fitted with bushings.

In the accompanying drawings, Figure l is a top-plan view ofthe main frame and housing of the minor axle, section being taken centrally in a horizontal plane through one of the journal-boxes of the drive-wheel. Fig. 2 is a side elevation ot' the same, looking from the platform side toward the drive-wheel, exhibiting the application of the box of the crank-shaft. Fig. 3 is a top sectional plan, through the housing of the minor axle and box ofthe crankshaft, in the plane indicated by the line z z of Fig. 2. Fig. et is a vertical elevational detail of one ot' the bushings, in place within one of the boxes of the main axle, viewed from the inside of the frame-work before the drive-wheel is set in place. Fig. 5 is a sectional elevational detail of the casing for the outer end of the box ofthe crank-shaft, section being taken through said box and crank-shaft on the line y y of Fig. 3, and the parts being viewed from the left-hand side of said Fig. 3, under the assumption, however, that such parts occupy the same vertical position which they are represented as occupying in Fig. 2. Fig. 6 represents, in perspective, my improved box for the crank-shaft; and Fig. 7 represents, in perspective, one `of the bushings ofthe axle.

Similar letters of reference indicate corresponding par-ts.

In the accompanying drawings, O is the main frame-a casting of rectangular form and of substantially the form represented. Within this frame is set the drive-wheel P by means ofthe axle m,journaled in the boxes Q, which contain bushings R, of substantially the form shown in Fig. 7-that is to say, provided on their inner face with a lug, S, which is fitted to take into a seat, T, upon the inner face of the journal-bearing. The object of this contrivance is to enable the ready removal of the bushing and its halt' or quarter rotation, in order to bring'its lng successively into dii'erent seats, of which a given series may be formed radially in the journal. These bushings are applied from the inside ot' the journal before the road-wheel is set in place. They are also applicable and are shown applied to thejournals of the minor axle. They are likewise applicable to other than harvester-journals.

U is the driving spur-wheel, which has the usual ratchet-connection with the drive-wheel, and which gears with the driving-pinion V on the inner end of the minor axle W, the outer extremity ot' which carries the bevel-wheel Y, which imparts motion to the bevel-pinion X, which is keyed to and drives the crank-shaft Z.

In Fig. 6 I have represented an improved box, a, which I employ as a bearing for the crank-shalt. It consists in a journal-box of substantially the form indicated in Fig. 5, the outer face of which is provided with a lug, b, designed to engage within a recessed projection, c, Figs. 2, 3, and 5, formed upon the removable half u' of the casing a, which 'depends from the main frame and holds the forward end of the crank-shaft box a removably in place. By the employment ot' this contrivance I obtain a readily removable and therefore replaceable bearing for the crank=shaft, and one which is readily set in the machine and taken out by the removal or application of the removable half a' ot' the casing u, the rear extremity ot' the box being simply fitted into a properlyshaped hole, c, Fig. 3, in the housing ai of the minor axle.

Having thus described myinvention, I claim and desire to secure by Letters Patent ot' the United States--v 1. As a new article of manufacture, a journal-box for the crank-shaft of the cutter-bar, consisting of a tubular casting (within which soY 1o with ajournal-box incasing it, and provided with a series of radially-arranged seats, within which the lug can be successively retained, as and for the purpose set forth.

In testimony whereof I have hereunto signed my name this 21st day of April, 1881.
